To all whom 'it may concern Be it known that we, THAunnUs F. BAILY and FRANK T. Corn, citizens ot the United l States, both residing at Alliance, in the The object of our invention is `to forni a' 'container for this purpose that will, when used with a pluralityl otsimilar containers, be sealed during4 its transit through the furnace by `the next adjacent container.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appeiided claims, it being understood that varions changes in the form, proportions, size and minor details of construction may be made Within the scope of the appended claims, Without departing from the spirit or sacrificing any oi. the advantages of the in.

In the drawings: Figure l is a View illustrating an electric Ifurnace with a plurality of our containers shown passing therethrough.

Fig. 2 .is an enlarged perspective view of one of our containers.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

In the heating of comparatively small articles manufactured from metal, such as small automobile parts and the like, it is necessary that the container be provided in which the articles are placed While in transit through the heating furnace.' Hcretoi'ore such containers have been made merely in the form of a metal box with a removable lid. It not only requires additional and unnecessary labor to place the lids upon these containers after they have been lled with the articles to be heat treated, but upon emerging from the heating furnace the containers are extremely hotfaml" no small Specication of Letters Iatent.

amount of difliculty is frequently experienced in removing the lids from the containeis. preciate that in the heat treating process of steel the quenching must he done almost 1nstantly after the articles being treated have been heated to a desired teni oratore. lhrough the difliculty experience in removing the lids t'ioni the containers it is 'he queutly necessary to run the container with -its load of articles through the furnace a second time since the time elapsing after the container emerges from the 'furnace until the lid can be removed is often great enough to allow the articles tocool too far below the desired temperature.

With the object of overcoming this undesirable feature, we have designed a con- Those skilled in the art will aptainer which requires no lid. i In the drawings l indicates a furnace which has an opening at 2 to admit articles to be heated and a similar opening at 3 to permit the discharge of the said articles from the furnace. At 4; is shown a motor connected by a suitable gearing 5 to operate a pusher arm G which pusher arm is designed to advance the articles to be heated through the turnacc, one container at a time.

Our container is shown at 7 and comprises a receptacle with an opening at 8 arranged so that when a plurality of the receptacles are placed'in a train, of each receptacle will be electually closed by the next adjacent receptacle. It will be obvious that by this construction no lid Will be. necessary upon the container.
